Apple’s next generation iPad 3 is to be built with thinner, lighter, longer lasting, and more expensive batteries. Pricing for the batteries from the manufacturers will be 20-30% higher in price than iPad 2 batteries from Simplo Technology Co. and Dynapack International Technology Corp., which are Apple’s contract suppliers for iPad and Macbook batteries. The new battery packs for the iPad 3 will start being manufactured the first quarter of 2012.

The good news? Ipad 3 battery packs will be delivered starting the fourth quarter of 2012, which might project a new iPad 3 by early spring 2013.
